Total Body Disruption
Total body disruption is the immediate and nonsurvivable destruction of the body. Commonly referred to as being "blown up", "blown apart", turned into "a (pink or red) mist" in modern culture, or "dashed to pieces" in older literature, total body disruption may be caused by being within or in close proximity to a powerful explosion. Total body disruption is the most severe type of blast injury. Total body disruption may also be caused by a fall from terminal velocity, or from being within a high-speed crashing object. Total body disruption is invariably fatal to humans and animals, since the brain (if not outright destroyed) is deprived of oxygenated blood, while other organs (if not outright destroyed) are deprived of the involuntary functions that are needed for the body to function. Incomplete, initially unidentifiable human remains caused by total body disruption may be referred to as "disassociated portions". See also * Decapitation * Dismemberment * Hemicorporectomy ...

Explosion
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blast Injury
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space. Classification Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary. Primary injuries Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract. Gastrointestinal injuries may present after a delay of hours or even days. Injury from blast overpressure is a pressure and time dependent function. By increasing the p ...

Terminal Velocity
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (''Fd'') and the buoyancy is equal to the downward force of gravity (''FG'') acting on the object. Since the net force on the object is zero, the object has zero acceleration. In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. As the speed of an object increases, so does the drag force acting on it, which also depends on the substance it is passing through (for example air or water). At some speed, the drag or force of resistance will equal the gravitational pull on the object (buoyancy is considered below). At this point the object stops accelerating and continues falling at a constant speed called the terminal velocity (also called settling velocity). An object moving downward faster than ...

Oxygenated Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blood a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomic Nervous System
The autonomic nervous system (ANS), formerly referred to as the vegetative nervous system, is a division of the peripheral nervous system that supplies viscera, internal organs, smooth muscle and glands. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, its force of contraction, digestion, respiratory rate, pupillary dilation, pupillary response, Micturition, urination, and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response. The autonomic nervous system is regulated by integrated reflexes through the brainstem to the spinal cord and organ (anatomy), organs. Autonomic functions include control of respiration, heart rate, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and certain reflex, reflex actions such as coughing, sneezing, swallowing and vomiting. Those are then subdivided into other areas and are also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decapitation
Decapitation or beheading is the total separation of the head from the body. Such an injury is invariably fatal to humans and most other animals, since it deprives the brain of oxygenated blood, while all other organs are deprived of the involuntary functions that are needed for the body to function. The term ''beheading'' refers to the act of deliberately decapitating a person, either as a means of murder or as an execution; it may be performed with an axe, sword, knife, machete or by mechanical means such as a guillotine or chainsaw. An executioner who carries out executions by beheading is sometimes called a headsman. Accidental decapitation can be the result of an explosion, a car or industrial accident, improperly administered execution by hanging or other violent injury. Suicide by decapitation is rare but not unknown. The national laws of Saudi Arabia, Yemen, and Qatar permit beheading; however, in practice, Saudi Arabia is the only country that continues to behead i ...

Dismemberment
Dismemberment is the act of cutting, ripping, tearing, pulling, wrenching or otherwise disconnecting the limbs from a living or dead being. It has been practiced upon human beings as a form of capital punishment, especially in connection with regicide, but can occur as a result of a traumatic accident, or in connection with murder, suicide, or cannibalism. As opposed to surgical amputation of the limbs, dismemberment is often fatal. In criminology, a distinction is made between offensive dismemberment, in which dismemberment is the primary objective of the dismemberer, and defensive dismemberment, in which the motivation is to destroy evidence. In 2019, Michael H. Stone, Gary Brucato and Ann Burgess proposed formal criteria by which "dismemberment" might be systematically distinguished from the act of "mutilation", as these terms are commonly used interchangeably. They suggested that dismemberment involves "the entire removal, by any means, of a large section of the body of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemicorporectomy
Hemicorporectomy is a radical surgery in which the body below the waist is amputated, transecting the lumbar spine. This removes the legs, the genitalia (internal and external), urinary system, pelvic bones, anus, and rectum. It is an extremely mutilating procedure recommended only as a last resort for people with severe and potentially fatal illnesses such as osteomyelitis, tumors, severe traumas and intractable decubiti in, or around, the pelvis. By 2009, 66 cases have been reported in medical literature. The most recent documented operation was in September 2019. Medical uses The operation is performed to treat spreading cancers of the spinal cord and pelvic bones. Other reasons may include trauma affecting the pelvic girdle (" open-book fracture"), uncontrollable abscess or ulcers of the pelvic region (causing sepsis) or other locally uncontainable conditions. It is used in cases wherein even pelvic exenteration would not remove sufficient tissue. Procedure The surgical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
